It's not just PA behavior, it's cyber bullying, at it's finest.

Some people, who do have PA issues(on one hand, many people have some PA moments, and on the other hand, that's just how some people really are), use passive aggression, because they aren't as in tune to themselves, and hence the inability to be direct.

Anther 'life theory' I have on this, is that it's both learned and in-grained in them to do that.

Which brings me to something that came up, this year, in therapy, for myself. I asked my therapist, what is 'manipulation' and how can I tell, if 1)I use that behavior and 2)how to spot it right away, so that I can move away, or deal with that from others.

The explanation, (well, he actually used a conversation example to show the difference), summed down to, non-manipulation is 'direct, frank, to the point.' Manipulation, beats around the bush, spins in circles and isn't direct and to the point.

To me, posting on facebook, what she did, isn't just passive aggression, but it's also manipulative.

Young adult, is about where, we start drifting away from the friends that we had. Sorry, you are going through this.
